FBI agent Martin Daniell says in court documents that Castle allegedly had several alcoholic drinks on Flight 562 from Las Vegas to Denver on Friday morning. He allegedly refused one flight attendant's request to stop using vulgar language and to quiet down, then told a second attendant she was beautiful.

Castle is accused of grabbing the second attendant's buttocks as she passed by his row. He was arrested in Denver after the flight landed.

Castle told investigators he is married and didn't make a pass at either flight attendant.
